Fibrillera

Fibrillera is a genus of flowering plants belonging to the family Asteraceae, commonly known as the daisy family. The genus is native to South America, with a significant number of species found in Argentina. Fibrillera plants are characterized by their unique inflorescences, which are composed of a central disc surrounded by ray florets. The disc florets are typically yellow or orange, while the ray florets are white or pale yellow. The leaves of Fibrillera species are often narrow and linear, and they are arranged alternately along the stem.

The genus Fibrillera includes approximately 15 species, with the most well-known being Fibrillera acaulis. This species is notable for its lack of a distinct stem, as the leaves and inflorescence arise directly from the base of the plant. Fibrillera acaulis is often cultivated as an ornamental plant due to its attractive flowers and compact growth habit.

Fibrillera plants are typically perennial, with some species being annual or biennial. They are adapted to a variety of habitats, including grasslands, rocky outcrops, and disturbed areas. The plants are often used in landscaping and gardening due to their low maintenance requirements and ability to thrive in a range of soil conditions.

The genus Fibrillera is named after the Spanish word "fibrilla," which refers to a fine thread or filament. This name is thought to refer to the fine, thread-like structures that make up the inflorescence of these plants. The genus was first described by the French botanist Jean-Baptiste de Lamarck in 1805.
